VPN：错误：Linux 路由添加命令失败

  • 772

我已经配置了一个 VPN 服务器

local 192.168.0.250
dev tun
proto udp
port 1194
ca /etc/openvpn/easy-rsa/keys/ca.crt
cert /etc/openvpn/easy-rsa/keys/server-vpn.crt
key /etc/openvpn/easy-rsa/keys/server-vpn.key
dh /etc/openvpn/easy-rsa/keys/dh1024.pem
server 10.8.0.0 255.255.255.0
ifconfig 10.8.0.1 10.8.0.2
push "route 10.8.0.1 255.255.255.255"
push "route 10.8.0.0 255.255.255.0"
push "route 192.168.0.250 255.255.255.0"
push "dhcp-option DNS 8.8.8.8"
push "redirect-gateway def1"
client-to-client
duplicate-cn
keepalive 10 120
tls-auth /etc/openvpn/easy-rsa/keys/ta.key 0
cipher AES-128-CBC
comp-lzo
user nobody
group nogroup
persist-key
persist-tun
status /var/log/openvpn-status.log 20
log /var/log/openvpn.log
verb 1

当使用以下命令从 linux 终端连接 openvpn 客户端时：

openvpn --config /home/user/myfile.ovpn

我有这个错误：

    以下路线是错误的。您不能添加前两个（也不需要手动添加），因为它们是您配置的隧道的 vpn ip 范围。（这两个也是多余的，因为 10.8.0.1 是 10.8.0.0 网络的一部分。）第三个是您的本地网络，将自动添加。因此，将它们全部删除并查看。

    push "route 10.8.0.1 255.255.255.255"
push "route 10.8.0.0 255.255.255.0"
push "route 192.168.0.250 255.255.255.0"

    请参阅：https ://openvpn.net/index.php/open-source/documentation/howto.html

    推送路由用于将路由添加到其他私有子网。

    # Push routes to the client to allow it
# to reach other private subnets behind
# the server.  Remember that these
# private subnets will also need
# to know to route the OpenVPN client
# address pool (10.8.0.0/255.255.255.0)
# back to the OpenVPN server.
;push "route 192.168.10.0 255.255.255.0"
;push "route 192.168.20.0 255.255.255.0"
